Subject: Solr recommender


A good way to find differing clumps of opinion based on user ids. Probably also want to consider number of reviews or we may get too many semi-obscure un-ratable videos. I wonder if filtering by some popularity percentile before clustering would solve that problem?

I'd probably try to cluster in advance, then at run-time randomly pick N (e.g. 10) clusters, and for each cluster randomly pick a video that's close to the centroid.
